Wi fi limited access issue in Dell inspiron 15R 3521
I am using Dell inspiron 15R 3521 laptop, operating system windows 8 64 bit. While i am connecting to internet via wifi, at first it is connected well but after few minutes it shows limited access,while other device still operated properly. I have already tried to install new drivers and changed the power management issue of the adapter, but still the problem is not solved. Please help me resolving the issue.
